Installing leiningen 2 on Ubuntu

Question

I have followed the instructions here:

leiningen.org

To install from the lein script. I now have:

~/.lein/self-installs/leiningen-2.4.3-standalone.jar

How do I now run leiningen? The instructions are not clear.

Answer 1

On ubuntu, its quite easy. Download executable file, make it executable and place it in system path.

$ wget https://raw.githubusercontent.com/technomancy/leiningen/stable/bin/lein
$ chmod +x lein
$ sudo mv lein /usr/local/bin

You can also move it any directory which is in system path.

$ lein -v

Answer 2

Posting this as it might help other users.

Follow the install instructions.

Please make sure the leiningen script that the install instructions is on your executable PATH.

The script is the entry point to leiningen commands, so it's still needed after the downloads are complete.

It takes care of setting up environmental variables, paths and everything else required to run leiningen, so you can use

lein <command>

instead of

java -cp <whatever>:~/.lein/self-installs/leiningen-2.4.3-standalone.jar ... clojure.main -m leiningen.core.main <command>
